What payment methods are available to pay my energy bill?

As technology advances, so do the methods used to pay bills.

Nowadays, most bills are paid via direct debit or online, but there are still plenty of people who pay their bills in a post office or by cheque.

Below is an overview of the different ways you can pay your bills, as well as some useful reminders to ensure you are saving money.

Direct debit

This is perhaps the easiest way to pay your bills. A direct debit is an agreement between you and your energy supplier that allows them to take money from your account at regular intervals. Your supplier can take what you owe them from your account but only after they have issued you with a bill. Direct debits are ideal for paying bills that vary from month to month.

Most suppliers offer discounts for setting up a direct debit as it makes things easier for all parties. Similarly, since your direct debit will never be late, you will never be fined for not paying your bill on time - provided there is money in your account at the time the direct debit is collected.

You can log into your account on your supplier’s website to set this up. You will need your supplier account number and your bank account details.


Most suppliers will offer you the option of viewing and paying your bill online on their website using a credit or debit card.

Credit/debit card

You can call your supplier to pay over the phone with a credit or debit card. Ensure that you have your account number to hand.

By cash

You can pay your bill at all retail outlets where you see a Payzone sign. You will need to bring your bill with you to pay it.


If you want to pay your bill by cheque, you will first need to complete the remittance advice slip on the bottom of your bill. Then you will need to make your cheque payable to your supplier and send it to them. You can find their address on your bill. Check out our guide which explains the differences between paying by cash or cheque.

Post offices/credit unions

Some suppliers accept payment via a post office or participating credit unions. You will need to bring your bill with you and you can then pay by debit or credit card, cheque or cash. You can pay bills for Airtricity, Bord Gáis Energy, Electric Ireland and Flogas in post offices. To pay your bills in the credit union, check with your local branch what services they offer.

Things to remember to save money

  • Ensure you pay your bill on time and in full to avoid late fees.
  • Paying by direct debit may mean you’re eligible for a ‘prompt payment’ discount as your gas and electricity supplier will know they are guaranteed payment.
  • Paying bills online may mean you are eligible for a paperless discount.
  • Energy companies can charge a premium on both their standing charge and unit rates to customers who pay their bill with cash or a cheque.
  • Please allow five working days for all payments to update on your account.
  • If you’re not happy with how much you are paying, you can always switch your supplier.
